To all whom t may concern:

Be it lrnown that li., GUSTAVE J. HOLL, a citizen of the United States, residen-t of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Holders for Projecting- Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which l have contemplated applying that principle, so as to vdistinguish it from other inventions.

My invention relates to object-holders for machines for projecting images of photographs, picture cards, ctc., such machines being usually designated as post card projectors.

The object of my invention is to provide a holder for said machine which will be economical of construction and eflicient in its operation.

Said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain means embodying my invention, 'the ,disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :.-Figure l represents, on a somewhat reduced scale, a rear elevationrof a double slide of the usual construction which is placed in the rear aperture of a projecting machine, said slide carrying two card-holders embodying my invention. Fig. 2 represents a rear eleva'- tion of a card-holder embodying my invention, showing the holding members in one position. Fig. 3 represents a view similar to that of Fig. L showing the holding members in a second position. Fig. 4L represents an end elevation of the holder viewed from the plane and in the direction indicated by the arrows in Fig.'2. Fig. 5 represents a vertical transverse section of the slide and holder, taken on the plane indicated by line V-V in Fig. l and viewed' in the direction indicated by the arrows.- vFig. 6 represents a transverse horizontal section taken upon the plane indicated by line Vl-Vl in Fig. 3 and viewed in the direction indicated by the arrows. Fig. 7 represents a rear elevation of my improved card-holder with hold'- ing members and actuating device removed. Fig. 8 represents a vertical section, taken upon the plane indicated by line VHVIH in Fig. 7 and viewed in the direction indicated by the arrows. Fig. 9 represents a detail elevation of one of the holding members detached. Fig. l0 represents a view similar to that of Fig. 3 showing a modified form of the holding meinbers and actuating means. Fig. 11 represents a horizontal section taken upon the line XI-Xl in Fig. 10 and viewed in the direction indicated by the arrows.

ln the illustrated embodiment of my invention, l have shown the latter mounted upon the slide l of an ordinary and usual construction. As is well understood by those skilled in the art, this slide is adapted to be moved horizontally in .suitable guide-ways (not shown) which are adjacent to an opening in the rear walls of the projecting machine (also not shown), such opening being of such size as would be completely covered by one-half of the slide and card-holder carried thereby. rlhis slide is shown of dimensions sufficient to carry two card-holders so that the card may be adjusted in one holder while the image of the other card is being displayed, also as will be readily understood by those skilled in the art. As is also common practice, the slide l is provided with two doors 2, Figs. 5 and 6, each of which is adapted to substantially close the opening in the machine and when so closing same forms a part of the rear wall thereof. rThese doors are of identically the same construction and the card-holders mounted thereon are also of identical construction, so that it will be necessary to describe in detail but one holder.

The slide l is preferably constructed of sheet metal and comprises longitudinal upper and lower members l, end members lb` and a vertical intermediate member l". These frame members therefore form two openings 8 in each of which la door 2 is mounted. Each such door is hinged at its lower end by means of pins l, 4f, Fig. l, which are secured thereto and pr jecting into suitable apertures in the members l" and l respectively. rlhe hinged axis therefore is horizontal. ln the upper corners of each of the openings 3 are located stops 5, 5, which prevent the door from swinging in wardly into the projecting machine. A

yielding latch Gis provided in fghe upper part of each opening and is adapted to detachably engage the upper edge portion of the corresponding door as shown in Figs. 1 and 5. As shown in dotted lines in Fig. 5, each door therefore may be swung outwardly so that its upper end is thrown outwardly free from the frame of the slide.

The central portion of each door is provided with a perforation and surrounding the exterior of this perforation and projecting vertically from the exterior surface of the door is a hollow bearing member 7, Figs. 5 and 6. Mounted in this bearing' member is a rotatable sleeve 3 which projects outwardly from the exterior of the bearing member and inwardly through and beyond the door, as shown in the drawings. To the inner end of this sleeve is iXedly secured, preferably by soldering or other suitable manner, a rectangular main card-holder frame 9 rIhis frame is provided with a centrally located circular depressed or dished portion 10, as shown in Fig. 7, and two laterally located depressed portions 11,

11. The depressed portions 10 and 11 extend outwardly and form seats, as will hereinafter appear, as well as stiffening ribs which serve to stiften the entire holder frame.

To the outer end of the rotatable sleeve 8 is secured a thumb wheel 12 by means of which it will be seen the said sleeve 8 may be turned and with it the main card-holder frame 9. rIhe movement of the said frame upon its axis is, however, limited by means of lugs 13, 13, which are formed in the door to project inwardly toward said frame and a lug 14 formed in the frame which projects outwardly, these lugs 13 being located from each other an angular distance of ninety degrees (90) and at such points as will permit the said frame to occupy a horizontal position when the lug 14 engages same. It will therefore be seen that the said cardholder frame may be swung throughout an arc of ninety degrees.

Each card-holder frame is preferably constructed of sheet metal and two opposite edge portions of same are turned over to form guide-ways 15, 15, as shown most clearly in Fig. 7 In these guide-ways are mounted two slidable card-holding members 16 which are concave and have those edges which are perpendicular to the guide-ways 15 turned over to form grooves 16 for the reception of the opposite edges of the post card, photograph or other object which is to be displayed, as shown in the left hand portion of Fig. 1. The concave construction of these lmembers is clearly shown in Fig. 4. The outward movement of the members 16 is limited by stops 17 formed upon the other opposite edge portions of the cardholdgr frame 9, as shown in Figs. 1, 2, 3 and Seated in the depressed portion 10 of the card-holder frame is a metal disk 18 whose inner surface is formed with two concentric spiral lands 19, forming spiral grooves 20. Each card-holding member 16 is provided with inwardly punched portions forming lugs 21 spaced so that they may project into said grooves. disk is provided with a square hole into which projects the squared end of a pintle 23 which is j ournaled in the interior of the sleeveV 8. This squared end is suitably secured by means of a nut 24, Figs. 2, 3 and 6. The outer end of this pintle projects beyond the thumb wheel 12 and is itself provided with a thumb wheel 25. It will therefore be seen that by grasping the thumb wheel 25 and rotating same, the pintle 23 and the disk 18 will be rotated. Such rotation will effect the actuation of the card-holding members 16 toward or from each other according to the direction of rotation of said disk, the lugs 21 traveling in the depressed portions 11. It will therefore also be seen that these card-holding members may be adjusted to assume positions in which they may hold either of the two opposite pairs of edges of a rectangular card or photograph which is oblong in shape.

In operating the above-described device, the slide 1 is placed in the guide-ways of the projecting machine in the usual manner. It being now required to place a post card or photograph in position in the holder, the catch .6 is liftedy so as to permit the door and the card-holder carried thereby to swing backwardly so as to extend beyond the interior of such slide. The thumb wheel 25 is then turned so as to cause the Vmembers 16 to recede a distance such as will per-- mit the card, photograph or other object to be held by its edges in the grooves 16a and The central portion of thisto lie in a position parallel with the faces of said members 16. The frame 9,V if not already in the proper position to bring the vertical and horizontal lines of the picture into proper position, is then turned by grasping the thumb wheel 12 so as to cause the members 16 to lie vertically or horizontally, as the case may be, when the door is closed, the stops 13 and 14 insuring the proper position for such turning.

It will therefore be seen from the abovedescribed construction that cards or objects of Varying dimensions may be held by the card-holder and may be properly displayed where the picture runs in the direction of the major dimension of the card or in the minor direction of the card or object.

In order to facilitate the centering of the card or photograph in the holder, the edge portions forming the grooves 16a of the member 16 are formed with notches 1Gb which are equidistant from each other and one of which is in the middle of such portion. These notches are particularly useful in centering the card when being adjusted and held in the groove, as Will be readily understood.

In Figs. and 11, I have illustrated a modified form of disk 18. The previously described disk consists of a cast or machined member in which the lugs are solid. In the form shown in Fig. 10, however, the disk consists of sheet metal from which are pressed inwardly projecting members 26 from opposite sides of slits 27 forming the required lugs. These lugs, necessarily, by reason of the above-described construction, are not continuous but are interrupted.y the interrupting portions 2S of the metal being staggered so as to impart a maximum of strength to the structure.

In the above-described manner I procure an eiiiciently operating and cheaply constructed card-holder for machines Which may be used in connection With various sized post cards, photographs or other objects and in which the direction in which the picture runs on such photograph does not prevent its being properly displayed.

Having fully described my invention, What I claim and desire to secure by Letters Patent is 1. In an object-holder for a projecting machine, the combination of a main objectholder frame provided With guide-Ways; tivo object-holding members slidably mounted in said guide-Ways so as to be reciprocable toward and from each other; and a rotatable actuating member provided With a spiral lug engaging said holding members, Whereby the rotation of said actuating member will eidect the approach or recession of said holding member.

2. In a projecting machine, the combination of a suitable support; an object-holder comprising a main object-holder frame, two oppositely disposed holding members slidable on said frame, a pintle mounted upon ,said support and extending through same,

an actuating member secured to the inner end of said pintle, engaging said holding members and adapted upon rotation to effeet the approach or recession of the latter, a rotatable sleeve surrounding said pintle mounted on and projecting through said support and having the main holder frame secured to its inner end, a thumb Wheel secured to the exterior end of said pintle; a thumb Wheel secured to the exterior end of said rotatable sleeve; and a lixedbearing member projecting from the exterior of said support and forming the bearing for said rotatable sleeve.
